ABSTRACT:
According to the invention, the conveyor control device, comprising an information carrier in the form of permanent magnets pressed into a nonmagnetic backing, and an information recording unit wherein pole pieces of a magnetic core are located on a common yoke with magnetizing coils. The opposite poles of the pole pieces are directed towards each other. In the process of recording the information carrier is introduced into a pole gap in the core. The information reading unit incorporates a nonlinear excitation circuit used to deliver current pulses to input electrodes of a magnetic field pickup, a decoder in the form of a diode bridge, a unit compensating for the magnetic field of the earth, a voltage source, and an output unit.
